Float Function Issues

I'm working on this problem for a project and have come across these errors. I'm guessing I can't use floats with functions like I could integers.... I was also wondering if for my last function there is an easier way to sort the numbers!

error C2601: 'Do_Sum' : local function definitions are illegal
(18): this line contains a '{' which has not yet been matched
(91) : error C2601: 'Do_Profuct' : local function definitions are illegal
(18): this line contains a '{' which has not yet been matched
(102) : error C2601: 'Do_Average' : local function definitions are illegal
(18): this line contains a '{' which has not yet been matched
(112) : error C2601: 'Do_Sort' : local function definitions are illegal
18): this line contains a '{' which has not yet been matched
(154) : fatal error C1075: end of file found before the left brace '{' at

This was the original problem!
o Create a menu that gives the user the following choices:

Options:
----------
1. Sum
2. Product
3. Average
4. Sort
5. Exit

o Input 3 float numbers. The program should include a loop (for more than one choice) and a switch statement (for options). Your program has to use modularization: each option should call a function

Here is my code! Any help would be appreciated!

Code:

	float v_1 = 0;
	float v_2 = 0;
	float v_3 =0;

	while (option != 5)

>> this line contains a '{' which has not yet been matched

I don't think it's that line, but you do have an unmatched brace. Find it and fix it.Then compile again and look at the errors. There is at least one more typo in your function definitions.

Code:

>			case 2:
>				{
>					cout << "The product of these numbers is" << Do_Product (v_1, v_2, v_3);
>					cout << "\n\n";
>					break;
>			case 3:

You're missing at the end of case 2. I think you can omit the braces entirely, since it's within a case.

Code:

>		temo = v_1
>		v_1 = v_2

You're missing semicolons here, and temp is misspelled. As for an easier way to sort the numbers, if you can use arrays, you could use the sort() function from the standard library.

One is not supposed to use braces

Code:

 { }

inside one's case statements.

Why not? It is necessary if you declare a variable within the case. If you don't, then the braces don't hurt.

Why not? It's helps organize the code. They are optional, but they don't hurt.

Braces can be put anywhere in a function body to separate out a section of code. This has the other effect that all local variables declared within the block are destroyed at the end of the block. If there are no local variables, then the braces serve only as a visual que.
